Single Super Phosphate (0-16-0-11S-21Ca) stands as one of agriculture’s most time-tested and versatile fertilizers, delivering essential phosphorus, sulfur, and calcium in a single economical application. With 16% water-soluble phosphate combined with 11% sulfur and 21% calcium, SSP provides comprehensive nutrition that supports root development, improves soil structure, and enhances crop quality across diverse farming systems.

I. Core Scientific Advantages

• Multi-Nutrient Composition
  Unlike simple phosphate fertilizers, SSP delivers three essential nutrients simultaneously: 16% P₂O₅ (phosphorus), 11% sulfur, and 21% calcium, addressing multiple nutritional requirements in one application .
• Immediate and Long-Term Availability
  The phosphorus in SSP is water-soluble and immediately available for plant uptake, while the calcium sulfate (gypsum) component provides gradual release of sulfur and calcium throughout the growing season .
• Soil Conditioning Properties
  SSP improves soil physical and chemical properties by enhancing structure, increasing water holding capacity, and promoting beneficial microbial activity .
• Phosphorus Fixation Reduction
  In phosphorus-fixing soils common in tropical regions, SSP helps convert unavailable nutrients into plant-available forms, making it particularly effective in iron- and aluminum-rich soils .

II. Precision Application Guidelines

Soil Application

• Field Crops: 250-400 kg/ha for cereals, cotton, and oilseeds
• Pulses and Legumes: 200-300 kg/ha to enhance nitrogen fixation through improved nodulation
• Sugarcane: 300-500 kg/ha at planting for root development and sugar content improvement

Application Methods

• Basal Application: Apply at planting or before sowing, incorporated into the root zone
• Band Placement: 5-8 cm below and beside the seed row for concentrated availability
• Broadcast: Uniformly spread and incorporated during land preparation

Soil Suitability
SSP is extensively suitable for diverse soil types including red earth, yellow earth, black soil, lateritic soils, and acidic conditions where phosphorus availability is typically limited .

III. Technical Specifications

IV. Documented Performance Benefits

Root Development and Crop Establishment
SSP promotes vigorous root growth and development, enabling better uptake of water and nutrients, particularly important during early growth stages .

Enhanced Biological Nitrogen Fixation
For leguminous crops including groundnut, soybean, and pulses, SSP ensures abundant nodulation, directly increasing atmospheric nitrogen fixation and soil fertility .

Quality Improvement Across Crops

• Oilseeds: Increases oil content in groundnut, mustard, and sunflower by 5-8%
• Sugarcane: Enhances sugar recovery and cane quality
• Cereals: Improves grain filling and protein content
• Fruits and Vegetables: Better storage capacity, color development, and marketable yield

Disease and Pest Resistance
Plants nourished with balanced phosphorus, sulfur, and calcium demonstrate increased resistance to pest and disease attack through stronger cell wall development .

V. Competitive Advantages

Economic Accessibility
SSP offers the lowest cost per kilogram among phosphate fertilizers, making it particularly attractive for small and marginal farmers seeking quality nutrition at affordable prices .

Sulfur Deficiency Correction
With 40% of agricultural soils showing sulfur deficiency, SSP provides the most economical source of this critical secondary nutrient .

Alkali Soil Reclamation
Continuous application of SSP helps reclaim alkali soils by improving soil chemistry and reducing exchangeable sodium levels .

Local Resource Utilization
SSP is the only phosphatic fertilizer that can effectively utilize indigenous rock phosphate deposits, supporting local manufacturing and reducing import dependence .

VI. Agronomic Importance Summary

SSP’s comprehensive benefits extend beyond simple nutrient supply to encompass:

• Improved soil aeration and water holding capacity
• Enhanced root growth for better drought resistance
• Increased protein content in pulse crops
